PDF417 CGI 1.2

PDF417, or Portable Data File 417, is a two-dimensional stacked bar code symbology capable of encoding over a kilobyte of data per label.

A CGI (Common Gateway Interface) Application is an application that a WWW server can execute. The easiest way to create barcodes on your web server is to use a CGI application that generates barcodes. It is enough to install just one executable file on the server. Embedding a barcode into an HTML page is as easy as using IMG tags.

Our CGI applications are written in C++ and are executable files, which ensures higher speed and lower load for the web server. You can use our CGI applications both on the Windows platform and on Linux with either IIS or Apache servers.

Examples:

If you specify the following parameters:

http://localhost/test/pdf417cgi.exe?data=HelloWorld&xdim=2&bcolor=ffff00&fcolor=0000ff

"HelloWorld" will be encoded in the PDF417 barcode, the x-dimension is 2 pixels, the background color is yellow, the foreground color is blue.

To get information about the PDF417 CGI application (and also the license information), just specify the parameter help:

http://localhost/test/pdf417cgi.exe?help=1

If the web server returns an error for some reason (for example, a CGI Error for a Windows server or an Internal Server Error for Linux), you may have specified some parameters incorrectly. Try specifying the parameters as shown below and you will get such an error.

http://localhost/test/pdf417cgi.exe?data=HelloWorld&w=1

As you can see, the width of the PDF417 image is set to 1 pixel. Of course, a PDF417 barcode image cannot have this size. To get debugging information, add the parameter debug and you will see an error message:

http://localhost/test/pdf417cgi.exe?data=HelloWorld&w=1&debug=1
